subtitled mkv can lead totem controls to stop working
Using GNOME/totem 3.32 with gstreamer 1.16
- download https://github.com/Matroska-Org/matroska-test-files/blob/master/test_files/test5.mkv
- open it in totem (needs gst-libav)
- turn off the subtitles
- try to open the video again (calling totem from a command line on it or from nautilus)
- the video doesn't reload properly, play/pause and the video slider don't do anything anymore
